Performance enthusiasts who prefer automatics will be interested in this new installation kit for Turbo Hydra-matic 4L60 four-speed transmissions originally installed '92-'93 Corvettes and '93 Camaros and Firebirds. This kit adapts the 4L60 automatic transmission for use in early-model computer-controlled and noncomputer-controlled vehicles such as bracket racers and off-road trucks. It can also be used when replacing a 700R4 automatic with a 4L60 transmission. The kit includes an instruction sheet, a throttle valvespring for carbureted engines, a normally closed Fourth gear clutch switch and a wiring connector for the torque converter. Technical Notes: This kit can be used on 700R4 or 4L60 automatic transmissions.
